Patented July 7, 1931 ISIDORE SIMON, OF CHICAGO, ILLINOIS HEELApplication filed November 28, 1928. Serial No. 322,396. I

My invention relates broadly to molded 'articles and has to do moreparticularly with shoe heels made of moldedor plastic mate rial, such asa phenol condensation product, lfihard rubber or the like. The inventionhas among its objects the production of a device of the kind describedwhich is attractive, of light weight, simple in construction, durable,and satisfactory for use wherever found applicable.

More broadly, it has as an object the pro duction of a heel formed of a'material that may 'be readily molded or shaped, which will be hard anddurable, impervious to moisture, having a high polish, and which willhave any desired color to match various kinds of leather or othermaterial from which shoes are formed, and which may be readily attachedto a shoe, and when so attached will 2 be firmly held in place. I

Many other objects and advantages ofthe construction herein shown anddescribed will be obvious to those skilled in the art from i thedisclosure herein given. 'To this end my invention consists in the novelconstruction, arrangementand combination of parts herein shown anddescribed, and more particularly pointed out in the claims.

Referring-now to the drawings forming.

and 2; v

Fig. 6 is a perspective view of an insert as used in the embodiment ofFig. 3.;

Fig. 7 is a perspective view of another in- 5 'sert used in the deviceofFigs. 1 and 2; and

Fig. 8 is a fragmentary detail section showing still another embodiment.

Referring first to the embodiment shown in Figs. 1 and 2, the numeral 10indicates a shoe heel formed preferably ofplastic material such as aphenol condensation product, vulcanized rubber, or other suitableplastic material.

As shown best in Fig. 2, the heel is formed with a concavity 12 in itsupper portionand with a central opening 13, so that the plastic body 10is substantially tubular. Spaced from the concavity 12 is' a shoulder 15upon which abuts a block 16 formed preferably of WO0(l,- or othersuitable penetrable material. It Will be seen thatthe block 16 fitssnugly in the central aperture of the plastic body and is curvedon itsupper surface as at 14 in conformity with the concavity 12.

Disposed between the block 16 and the plastic body 10 is an insert 17formed preferably of sheet metal or the like, and shown best in Fig. 5.This insert extends into the plastic body. as at 18 and has a peripheralridge 20 formed integrally therewith. Obviously, the ridge 20, which maybe in the form of any suitable irregularity, may be in the firm ofnodules or other irregularities. The function of this ridge is to securethe insert 17 to theplastic body. Furthermore,- it will be obvious thatthis ridge or irregularities may be entirely eliminated, if desired, andthe-insert merely made to extend into the plastic body, as shown at 18.However, I have shown both means for securing the insert to'the plasticbody.

The insert 17 hasa peripheral flange 22 which is crimped over so as tosecurely engage the block 16 forretaining it in the central cavityof-the plastic body.

. Disposed in the central cavlty of the plastic body, adjacent the lowerportion thereof,

is another block 23, similar in composition to the block 16, this blockbeing secured in a cup-shaped member 25 formed preferably of sheet metaland abutting against a shou1- der 25 in the plastic body. The cup-shapedmember 25, as best seen in Fig. 7, .hasa pe-' ripheral flange 26 whichextends around the bottom of the molded body 10 so as to form a guardtherefor, and has a peripheral edge 28 for securing it to the moldedbody, which ridge may be reversed for securing the block 23 in place.Apertures 29 are formed in the insert 25 through which screws 30 arepassed for securing the block 23 to the cup-shaped member. bottom of theheel by means of cement, nails, or other suitable means.

It will be obvious, of course, that the block 16 will serve as a baseupon which may be tacked the leather portion of the shoe indicatedgenerally at 35 (Fig. 2) and that the flange 26 of the insert 25 willserve to protect the plastic body when a tool is applied to the lowerportion of the heel for removing the lift 32.

Inthe manufacture of the heel such as is described above, the plasticbody 10 is formed in a mold of suitable shape and the inserts 17 and 25are preferably molded into the plastic body 10. It will be readilyapparent to these who are familiar with the art that the central cavity13 is filled with a suitable core, during the molding operation and thatthis core is removed after the plastic body has hardened. The block 23is then driven into the insert 25 and secured therein by means of thescrews 30 and the block 16 is driven into its insert 17 and the flange22 of the insert is crimped over so as to secure the block therein. Theheel is now ready to have the lift 32 applied thereto either by means oftacks or cement, and may then be applied to the shoe by means of tacksengaging the block 16.

Referring now to the embodiments of Figs.

- 3 and 6, there is provided a plastic tubular rality of teeth 47, theseteeth being preferably struck out from the main body of the insert 45.Disposed within the insert and securely retained therein by means ofteeth 47 is a block 48 preferably formed of wood or other penetrablematerial.

While the insert 45 is shown as secured to the plastic body 40 by meansof a peripheral ridge 46, it will be obvious that the insertmay be madeso as to extend into the plastic body as in the embodiment of Fig. 2, isso desired.

Disposed in the central cavity 41 adjacent the lower end of the plasticbody 40 and abut ting against the shoulder 43 is a block 50 ofpenetrable material and interposed between the block 50 and the plasticbody is a metal- A lift 32 may be secured to thelic insert 51. Thisinsert is substantially similar to the insert 45, having struck-outteeth 52 integral therewith and an integral ridge or groove 53 forretaining the insert in the inserts are retained therein by means of theperipheral ridges 46 and 53. The insert 51 has a peripheral flange 56extending around the lower edge of the plastic body so as to protect thesame substantially in the same manner as the flange 26 in the embodimentof Fig. 2.

In the manufacture of the heel shown in Fig. 3, the plastic body ismolded in a manner substantially similar to that of the otherembodiment, the inserts 45 and 51 being molded into the plastic body. Itwill be readily understood that the inserts 45 and 51 are preferablyfirst formed with the teeth formed therein but-not struck out therefromto any appreciable extent. Hence the usual core may without difficultybe placed within the central cavity and removed therefrom. After themolding step, the teeth are made to project from the walls of theinserts by inserting a tool thereunder and forcing them out, or by othersuitable means. i

The embodiment shown in Fig. 4 comprises a plastic body 60 which issubstantially similar to the plastic bodies of the other embodiments-andhaving a block 61 and a metallic insert 62 disposed in the upper portionthereof, all substantially similar to the embodiment of Figs. 1 and 2.In this embodiment, however, there is a central cavity 64 which does notextend entirely through the plastic body, this body being closed at itslower end as shown at 65. A plate 66 preferably of metal, or the like,is secured to the bottom of the plastic body by means of integral struckout portions 67 penetrating the plastic body, or by other suitable;means. A lift, or rubber heel, 68, may besecured to the bottom plate 66by means of cement, screws, or the like.

It will be readily understood that in this device the plastic body ismolded substantial ly as in the other embodiments with the insert 62 andthe plate 66 secured thereto in' the molding operation. In thisembodiment the plate 66 serves to protect the bottom of the plastic bodyfrom injury by a tool when an old lift is removed therefrom.

In Fig. 8, I have shown a tubular plastic body 70 similar to that ofFigs. 1 and 2, with a penetrable block 72 retained therein by means of ametallic insert 73. This insert is similar to the insert 17, except thatit'has a peripheral flange 74 coacting with a groove 75 in the block 72for retaining the latter in place.

tion of colors, requires no covering, and is of light weight withouthaving any of the disadvantages of wood or other similar material.

Having thus described my invention, it isobvious that various immaterialmodifications may be made in the same without departing from the spiritof my invention;
